SHIM (Mitsubishi MB12003-42321)

A worn shim can allow excessive clearance between components, leading to accelerated wear or misalignment. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB12003-42321. A shim is a thin, flat component used to fill gaps or adjust spacing between mating surfaces. Its plain mechanical function is to take up slack and maintain precise alignment under load. A common generic failure consequence is that a missing or degraded shim can cause vibration, noise, or uneven load distribution. Keeping a shim in sound condition helps preserve the intended fit and reduce component stress. Verify the serial number or application, then call (562) 693-7748.
